YVR-SEA "Weather Bomb"

Sun Sep 29, 2013 11:23 pm

A weather event being called a "weather bomb" by media is set to hit SEA-YVR with hurricane force winds and lots of severe turbulence.

Keep safe out there folks!

Anyone know of any weather diversion or IROPS at these airports yet?

Not to say it's not going to be a doozy, but those are not "hurricane force" winds.

I'd be more worried about the 2-3 inches of rain.

This is a big and high, Portland to Vancouver BC, likely north. Not with real high winds but higher than we have had for a while. Us folks in SW WA are battening down hatches, fired up aux. heat, checked generator, and etc., wind scheduled to peak at 8pm.

The good news! It's snow at the top of Whistler.

100 km/hr gusts don't quite reach hurricane levels (119 km/hr is the bottom) but they can do some real damage. I'm watching the trees in my back yard waving around right now, and the worst is still to come.

Yeah, it's been blowing hard all weekend here in Portland. We've had 2"/5cm of rain since Saturday morning, with more coming down and still more to come overnight.

Johnson Creek will flood, and the idiots who've bought cheap homes in the flood plain will get flooded out.

Someone told me that this was remnants of Typhoon Usagi, but I don't know about that.

I looked at Weather Channel because I'm over in Calgary and have a 6am Monday flight. According to them, winds should start dying down at YVR about 3am.

I assume that's because the storm will be crossing the Rockies by then.

2-3" of rain is a good amount in Portland and Seattle, but it's nothing they can't handle. Supposedly this weekend was going to get 5-8" in Seattle and 4-7" in Portland. I'm sure as hell glad I left Friday night. It was blowing pretty nice in the valley when I left my office but no real rain. Traffic sure sucked though. A friend of mine was in Seattle this weekend and said he was dripping wet after walking a block. Sucker.

This is correct. It's not uncommon for them to get sucked up and sent across the pacific.

This "bomb" phrase was coined by the NWS, only they called it a "meteorological bomb." It's actually a real phrase: http://en.wikipedia.org/wiki/Bomb_(meteorology)

The reason this storm was more dangerous than one in December is most of the trees still have their leaves.

Here's the discussion from NWS Seattle at 9a this morning:

".SHORT TERM...STRONG JET STREAM WINDS ARE CUTTING ACROSS THE PACIFIC
AT OUR LATITUDE...WITH AN UNSEASONABLE AMOUNT THERMAL GRADIENT
ACROSS THE JET STREAM FROM NORTH TO SOUTH. SATELLITE IMAGERY NOW
SHOWS A BAROCLINIC LEAF...WHICH IS A SIGNATURE THAT TYPICALLY OCCURS

CENTER. IN FACT...ALL MODELS SHOWS DEVELOPMENT THAT MEETS THE

Johnson Creek will flood,

It still is coming down in Portland, lots of folks without power in the tri county area and flooding in the usual places, trees down all over the place due to soaked soil and soaked trees with leaves still on them. I was under the impression the million dollar Johnson Creek project was supposed to relieve the flooding that usually happens there. It's windy enough downtown, here in the Pearl District.

Well, I'd call it somewhat of a "Weather Bust" here in Auburn, WA. We did have some pretty heavy rain earlier tonight, and the winds were somewhat breezy, but right now its calmer than it's been in a few days.

We've still got time, though.

That's correct. Here on the San Juan Islands the wind was not too bad. Didn't keep us awake last night; power didn't go out and even some small planes braved the winds aloft! The rain was (and has been) the big deal. We've had lots of precipitation over the past week.

I don't complain about the rain. We moved to the San Juans from Southeast Alaska where it is typical in October to get 31 inches of rain for the month. One inch a day.

As of 0830 Monday, all is calm.

We generally get a nice blow every October.. some worse than others.. but the press like to trumpet each as Armageddon the days before and waste time with picturing one tree that blew over.. 50% of the time it's just another Pacific storm by February they don't even bother reporting ..

I was watching radar and satellite reports last night, and by my 101 level weather interpretation the storm angled up about a hundred miles from where forecasts had it coming ashore, very north on Vancouver Island versus central part of island. We did not get any of the really major forecast gusts here in SW WA.

This was a storm that came about 2 months earlier than usual, that is why it's hyped up. You are correct, by February this wouldn't be an event at all.

Yeah, still gusty here but not like it was... we've had 3 full inches/7 cm of rain here in Sellwood/Moreland since Saturday. I saw some trees down in Garthwick on Sunday, but none in my neighborhood. Power went out for a few moments on Saturday evening, but only flickers yesterday.

I think some of that storm made it's way to North Dakota. Supposed to get some wicked winds tomorrow. It sounds like it has already picked up. The TAF for GFK is saying 27G35kt tomorrow. Nothing like what it sounds like the Pacific NW got. But still pretty strong!

Unless they build a ten foot dike all the way along Johnson Creek it's gonna keep flooding. Too much development in SE, they paved over everything around the creek so everything runs instantly right into the waterway.

No, but then two flakes of snow will fall on the Sunset Highway and the news will be on the WINTER STORM OF THE CENTURY kick.

Here at BIL we had strong winds all day yesterday (9/30). Some slight damage but nothing really out of the ordinary for high winds.

I can envision Tracy Barry up on Sylvan overpass reporting every 5 minutes about how many flakes are in the air. LOL!

Based on past years that have early winter storms, the winter tends to be wetter and colder than usual, so we may see more than a quick dusting of snow here in the valley.

Which is why I'm glad I live downtown, it is an easy streetcar, bus or max to anywhere in the metro. I moved to the Pearl the last time we had a bad snow storm, 2009? over a foot for a week solid... It was the year we moved here from SFO.

Interesting. I know there are two remaining Mars water bombers. Went up to Sproat Lake to see them but they were not there. Maybe out fighting fires as it was last summer I went to the Lake. Any idea where they might be?
